IOM Wants ME/CFM Name Changed to Systemic Exertion Intolerance Disease (SEID)

The US Institute of Medicine’s (IOM) committee on the Diagnostic Criteria for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) has recommended that the name ME/CFS be changed to Systemic Exertion Intolerance Disease (SEID). It has also recommended that the disease be assigned a new code in the current WHO International Classification of Diseases, tenth edition (ICD-10). In addition, five main symptoms have been identified and new diagnostic criteria developed.

This was revealed in a press release embargoed until 11 am EST (4 pm GMT) today.

Systemic Exertion Intolerance DiseaseThe press release shares information from the committee’s 235-page report titled Beyond Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Redefining an illness, and also embargoed until 11 am EST today. The official release of the report will be webcast live.

The Disease

According to the IOM press release, ME/CFS is “a legitimate, serious, and complex systemic disease that frequently and dramatically limits the activities of affected individuals” and it “needs proper diagnosis and treatment.”

Between 836,000 and 2.5-million Americans suffer from ME/CFS and alarmingly, about 84 to 91 percent of those with the disease are not diagnosed.

The report states (as ME/CFS sufferers know only too well),  that while symptoms can be treated, the cause remains unknown – although symptoms are sometimes triggered by infection – and there is no known cure.

Less than one-third of medical schools include ME/CFS-specific information in the curriculum.

Another alarming statistic highlighted is that 67 to 77 percent of patients reported it took more than a year to get a diagnosis.

The cost implications are also enormous, with direct and indirect costs of ME/CFS to society estimated at $17-billion to $24-billion annually, $9.1-billion of which has been attributed to lost household and job productivity. 

Diagnostic Criteria for ME/CFS

The committee has developed five new diagnostic criteria that coincide with the five main symptoms they identified.

According to committee chair, Ellen Wright Clayton, Craig-Weaver Professor of Pediatrics and professor of law at Vanderbilt University, “Diagnosing ME/CFS often is a challenge, and seeking and receiving a diagnosis can be frustrating due to the skepticism of health care providers about these patients and the serious nature of their disease.”

She said the new criteria would make it easier for clinicians to recognize and accurately diagnose patients in “a timely manner.” It would also enable a large percentage of currently undiagnosed patients to receive appropriate care.

Diagnosis requires patients to have three core symptoms:

  1. A substantial reduction or impairment in the ability to engage in pre-illness levels of activities – and this should persist for more than six months and be accompanied by often profound fatigue that is not the result of ongoing excessive exertion and not substantially alleviated by rest.
  2. The worsening of patients’ symptoms after any type of exertion, including physical, cognitive, or emotional stress that is known as “post-exertional malaise”
  3. “Unrefreshing sleep” – which means that sleep doesn’t help them feel rested or less fatigued.

Additionally, at least one of the two following manifestations is also required:

  1. Cognitive impairment.
  2. The inability to remain upright with symptoms that improve when lying down. This is known as orthostatic intolerance.

“These symptoms should persist for at least six months and be present at least half the time with moderate, substantial, or severe intensity to distinguish ME/CFS from other diseases,” the press release states.

The committee recognized that proposed criteria will not improve the diagnosis and care of patients unless health care providers use them. For this reason it recommended that the US Department of Health and Human Services (HHS) should develop a toolkit for screening and diagnosing patients with ME/CFS in a wide array of clinical settings, including primary care practices, emergency departments, and mental health clinics.

Recommendation to Rename the Disease

To convey the complexity and severity of ME/CFS, the committee recommended that the disorder be renamed “Systemic Exertion Intolerance Disease” (SEID).

“The committee, along with many ME/CFS patients, believed the term ‘chronic fatigue syndrome’ perpetuates misunderstanding of the illness and dismissive attitudes from health care providers and the public.  The term ‘myalgic encephalomyelitis’ was deemed an inappropriate name by the committee, because myalgia, or muscle pain, is not a core symptom of the disease and because there is inconclusive evidence of brain inflammation in ME/CFS patients.

SEID captures the central characteristic of the disease that exertion of any sort can adversely affect several organ systems and many aspects of patients’ lives, often seriously and for long periods.

“Individuals who meet the proposed criteria, whether or not they have already been diagnosed with ME/CFS, should be diagnosed with SEID, the committee said.”

As the press release highlights, the committee also found that research on ME/CFS is urgently needed, especially given the number of people affected, because too little is known about the causes, development, and progression of the disease, or about effective treatment.

“Future research could lead to findings that refine the diagnostic criteria and understanding of ME/CFS subtypes.”

For this reason, the committee recommended that a multidisciplinary group re-examine the proposed criteria after five years or sooner if firm evidence supports the need for modification.

“This disorder is often devastating for those who suffer from it,” said Victor Dzau, president of the IOM.  “The diagnostic criteria offered in this report are intended to promote prompt diagnosis for patients and enhance treatment, as well as improve public understanding of the disease.”
